FLY-

FAN.

SPECIFICATION forming part of Letters Patent No. 258,785, dated May 30,1882.

Application filed March 16, 1882. (No model.)

To all whom "it may concern:

Be it known that I, THOMAS A. MARTIN, a

citizen of the United States, and a residentof Evansville, in the countyof Vanderburg and State of Indiana, have invented a new and valuableImprovementin Fly-Fans, (on PatentNo. 251,612,) and I do hereby declarethat the following is a full, clear, and exact description of theconstruction and operation of the same, reference being had to theannexed drawings, making a part of this specification, and to theletters and figures of reference marked thereon.

Figure 1 of the drawings is a representation of a vertical sectionalView of my improved flyfan, and Fig. 2 is a face view of the same.

This invention has relation to fly-fans; and it consists in the novelconstruction and arrangement of parts hereinafter fully described, andparticularly pointed out in the claim.

In the accompanying drawings, the letterA designates the rock-shaft,which is of squared or prismatic form.

B B indicate thejointed arms of the fan 0, the sections of which arepivoted together at cl, and e represents a stiffener or latch-arm,which, when the sections are in line with each other, serves to holdthem in this position. The fan can be easily raised by turning the lowersections, I, upward, and it the spring-latches c are sufficiently strongthey will serve to hold the fan, which is designed to be of very lightmaterial, in the raised position. The upper section, J, of each arm isprovided with an angular aperture, h, through-which the rock-shaftpasses. The arms are therefore adjustable on the rock-shaft to or fromeach other, to suit the size of the fan. When adjusted, the position ofthe arms is secured by means of the setscrews k.

L indicates an arm extending upward from the rock-shaft. This arm isalso provided with an angular aperture, h, to engage the 'rockshaft, andhas a lateral threaded bolt or stud, l, on which weight-nutsw arescrewed. These weight-nuts may be of different weights, or there may beseveral, designed to be adjusted on the stud of the arm L, until theweight ofthe fan and its arms is counterbalanced; or there may be a slotmade in the arm, and the threaded bolt may be adjustable in said slot toor from the rock shaft, according to the weight of the fan, the boltbeing secured in position by the weight-nut. The spring-latch cextendsacross the joint, being secured to the lower section and bearing on theupper section.

An automaticvfly-fan adapted to be swung up out of the way when not inuse is not broadly new, and no broad claim for such a construction ismade herein.

Having described this invention, what I claim, and desire to secure byLetters Patent, 1s-

In a fly-fan having a horizontal rock-shaft rectangular in form, theadjustable fan-arms consisting of the arm-sections I J,jointed at d, andthe latch 0, extending across the joint, in combination with thecounter-balance L, extending upward from the rock-shaft, the threadedbolt I, and the weight-nut w, engaging the same, substantially asspecified.

In testimony that I claim the above I have hereunto subscribed my namein the presence of two witnesses.
